The Stars Are Overjoyed for Their Oscar Nominations

"It is with much consideration and a heavy heart that we are announcing that after 10 years of a loving relationship, the decision was made to move on without each other," a rep for the couple told E! News. "We will carry with us the memories of a relationship grounded in love, laughter, support and friendship."

"We have experienced some of life's greatest joys and toughest challenges together, and our decision to be apart can never diminish that. We want to thank everyone for their support and we ask that our privacy be respected as we move forward."

News of the couple's breakup may come as a shock, considering that their relationship seemed stronger than ever while Zohn was battling not one, but two bouts of Hodgkin's lymphoma.

Back in 2011, the reality star duo talked about a "survivor" couples guide that they were working on together, and dished about their relationship.

"I think cancer is a hard battle to fight alone or with another person at your side, but I will say having someone to pick you up when you fall, stand by your side through every appointment and delivery of bad news is priceless," Morasca told Glamour. "Being a caretaker is, and never will be, an easy job, in fact it is that hardest job in the world and many times a thankless job. You have to be the pillar of strength even when you feel like you are crumbling to pieces inside."

"At the same time while he will probably say that I was his strength and vital to his recovery (or at least I hope he will say that) I can say that being able to see him struggle but never give up even when cancer was trying to take over his body was a life-changing experience for me," Morasca continued. "I gained a whole new level of respect for him, and learned a lot about myself and how far we can push ourselves."

When Zohn's cancer returned in 2012, Morasca talked to E! News about how they were coping with it.

"For Ethan, the hardest part would be fighting for the ultimate prize, which is being able to live," Morasca said. "The hardest part for me is to try and maintain a relationship in the midst of a war. It is hard at times to remain caring and considerate and to keep perspective."

"I am trying to make sure when all of this is over that Ethan and I are in the best place, she continued. "That I put in the work and that he put in the work, even when it was exhausting. My goal is to start our lives together. Am I scared and nervous and anxious? Yes!"

The reality star duo also competed together on "The Amazing Race" and starred on their own show, "Everyday Health."
